When Streptomyces viridosporus was grown in batch culture on mineral salts – glucose medium and under oxygen, aerial mycelium formation and sporulation were suppressed. Under these conditions, biodegradation of soil or synthetic humic acids (expressed as the rate of decolorization of growth medium and the loss of radioactivity of labeled melanoidin, respectively) increased. Concurrently, both the catabolic activity of cells (expressed as peroxidase production, measured by the oxidation of N,N,N′,N′-tetramethyl-1,4-phenylenediamine as substrate) and the excretion of siderophores were stimulated.Key words: humic acid biodegradation, melanoidin mineralization, Streptomyces viridosporus, peroxidase, siderophore.
